ABSTRACT:
In a ring-type spinning or twisting frame in which the ring stator and the rotor are coupled to one another with rolling members inserted therebetween in grooves formed facing each other in the rotor and the stator, braking means being provided between the stator and the rotor, the improvement is disclosed according to which an annular bracket is provided beneath the annular cage, the seats for the rolling members having appropriately sloping edges, so that when the spinning frame starts its rotation, the annular cage is lifted, whereas the contrary occurs when the spindles are stopped, so that the cage is allowed to fall due to its own weight and the rotor is stopped instantaneously.
